Colona erecta Plant Care

Colona erecta (Colona erecta) belongs to the Malvaceae family within the Colona genus.

Colona erecta displays a bushy shrub, spreading growth habit, reaching up to 3 ft tall with a spread of approximately 4 ft. Colona erecta produces showy, colorful blooms in shades of pink, purple, or white.

Leaf size: approximately 6 inches.

Water a young or newly planted Colona erecta every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Colona erecta thrives in full sun to partial shade.

Colona erecta tolerates temperatures of 60–80°F. Colona erecta prefers humidity levels of 40–70%.

Well-draining loamy soil with added compost for nutrients. Good drainage is essential for Colona erecta to prevent waterlogging, which leads to root rot and fungal issues.

Feed Colona erecta every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with full sun to partial shade and well-draining loamy soil with added compost for nutrients. Avoid low spots where water collects after rain.

Colona erecta is suited to USDA Zone 13a.

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

Colona erecta can spread to about 4 ft (1.2 m) and reach about 3 ft (1 m) tall. Space plants about 4 ft (1.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Colona erecta while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the shrub in one year.

Colona erecta is frost-tender (hardy to USDA zone 13). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Colona erecta can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to colona auriculata plant care, which shares the same genus.

Colona erecta is susceptible to aphids, spider mites, whiteflies. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Colona erecta grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. In cooler regions, grow Colona erecta as a houseplant or bring it indoors before the first frost.
